dm: remove support for stacking dm-mq on .request_fn device(s) Remove all fiddley code that propped up this support for a blk-mq request-queue ontop of all .request_fn devices. Testing has proven this niche request-based dm-mq mode to be buggy, when testing fault tolerance with DM multipath, and there is no point trying to preserve it. Should help improve efficiency of pure dm-mq code and make code maintenance less delicate. Signed-off-by: Mike Snitzer <snitzer@redhat.com>
